If you made a lot of short trips it will really kill your mileage. For instance this is my schedule.

7:15 AM Start car.
7:25 AM drive to school.
7:40 AM arrive at school and shut car off.
3:05 PM Start car
3:10 PM Drive home.
3:20 PM Arrive home. Shut off car.
3:35 PM Start car, Drive to work.
3:36 PM Arrive at work. Shut off car.
7:00 PM Start car
7:05 PM Drive home
7:06 PM Arrive home, shut off car.

Doing that gives me like 13 MPG, driving like a grandma. I get around 200 miles before I get a little past 1/4 tank.

On weekends I drive longer than 30 minutes at a time and romp on the gas sometimes, I get between 17 and 20. This is all local driving with lots of stop lights. I now cut back and I dont drive to school as often to save gas and frequent starts.

Try some fuel injector cleaner, change your air filter if it needs it, fill up your tires to at least 33 PSI.
